Subject [jira] [Commented] (AMBARI-21674) Ambari to support Hybrid cluster

David Clissold commented on AMBARI-21674:
-----------------------------------------

We are very interested and motivated to see this functionality work in Ambari, and would very
much like to hear opinions and suggestions from the Ambari community about the best approaches
to this.  We have a few people that are prepared to focus on this area, but we would like
to make sure we are focused on the right areas and are on the right track.

To anyone watching this:  Has there been any attempt to start on this hybridization feature
before?  Anyone have any recommendations, or caveats that we should watch for?

> We have been exploring Hybrid hadoop cluster recently. By hybrid, i mean the nodes in
the cluster have different platform architectures. Some nodes are intel x86_64 , some are
IBM Power ppc64le., and so on. Right now Ambari doesn't have this hybrid support. It selects
the repo based on the machine where it is installed and then ask the users to add the nodes.
I think this order has to be changed as the first step to provide hybrid support in Ambari.
> We were actually able to bring up a hybrid cluster using some hacks (not so good) like
manually configuring the yum repos according to the arch, installing the rpms before ambari
does and also manipulating the JAVA_HOME variable. We also ran some examples like terasort
without any issues.
> So the thing here is we kind of starting to work on making Ambari provide a smooth hybrid
support which requires some design changes. We very much welcome Ambari community to provide
some ideas, patch contributions, or whatever way you can help us on.
